What is the holiday tomorrow

On December 11, the church calendar commemorates The Day of Remembrance of Saint Daniel the Stylite. Saint Daniel was one of the most renowned ascetics who spent his life in prayers and fasting on special platforms, renouncing ordinary living conditions for the sake of spiritual feats. As a disciple of Saint Simeon the Stylite, he gained fame for his gift of wisdom, foresight, and miracle-working.

On this day, Ukraine and the world celebrate The Day of the Establishment of the United Nations Children’s Fund UNICEF. It was on December 11, 1946 that the United Nations General Assembly established the United Nations International Children's Emergency Fund (UNICEF). After World War II, millions of children were left orphaned, suffering from poverty and hunger. UNICEF was created for the urgent assistance of these children.

Additionally, December 11 marks International Mountain Day, proclaimed by the UN General Assembly in 2002. The purpose of this day is to raise global awareness about the importance of mountain ecosystems and the lives of the people who live there. Mountains occupy about 27% of the Earth's surface and are a source of fresh water for more than half of the planet's population.

Moreover, December 11 is celebrated as World Asthma Day, aimed at drawing public attention to the issues faced by people living with this chronic respiratory disease.

December 11 is also marked as International Tango Day. The holiday was chosen in honor of Carlos Gardel, the legendary Argentine singer and composer who made tango world-famous. This holiday was first celebrated in 2009 thanks to the initiative of Argentine cultural organizations with the support of UNESCO.

This day is important not only from a religious perspective but also as a reminder of the social issues faced by children and people living in mountainous areas. The holidays related to tango and mountain culture emphasize the importance of the heritage and traditions of various peoples. Given the prolonged conflicts and challenges, it is essential to remember humanitarian initiatives that help improve the lives of people around the world.
